Scope

This part of GB/T 7165 applies to equipment for simultaneous, delayed or sequential measurement of all forms of radioactive iodine. When sampling the effluent for measurement, the iodine attached to the aerosol is typically collected by a pre-filter and analyzed separately in the laboratory to provide a complete measurement. The radioactive iodine monitor shall have the following functions: - measure the volume activity of iodine and iodine compounds in the gaseous effluent stream and the total activity of discharged radioactive iodine; When the threshold value is reached, an alarm signal is activated. These devices measure the activity of other radionuclides present in the gaseous effluent, including natural radionuclides. Screening for other nuclides is important when measuring low levels of radioactive iodine. In chimneys or ventilation ducts, this section considers both the use of activated carbon as a sampling medium for iodine and the direct measurement of iodine. The purpose of this section is to specify specific standard requirements for iodine monitors listed in Chapter 4, including technical characteristics and general test conditions, and to give examples of possible methods. GB/T 7165.1-2005 specifies the general requirements, technical characteristics, test methods, radiation characteristics, electrical characteristics, mechanical characteristics, safety characteristics and environmental characteristics of this type of equipment. Unless otherwise stated, these requirements apply to this section.
